CALGARY, ALBERTA--(Marketwired - Sept. 6, 2017) - Pengrowth Energy Corporation (the "Company" or "Pengrowth") (TSX:PGF) (NYSE:PGH) today announced that it has entered into an agreement for the sale of its remaining Swan Hills assets in North Central Alberta for total cash consideration of $150 million, subject to customary adjustments. When combined with the approximate $18 million deposit from the initial sales process which was terminated on July 11, 2017, total consideration for the sold assets will be approximately $168 million before closing adjustments.

The assets to be sold generated average daily production of approximately 5,060 barrels of oil equivalent per day (boe per day) (weighted approximately 82 percent towards liquids) during the second quarter of 2017 and had 31 million boe of Proved plus Probable (2P) reserves assigned to them as at December 31, 2016, according to the independent reserve evaluators GLJ Petroleum Consultants Ltd.

The effective date of the sale is January 1, 2017 and closing is expected to occur during the fourth quarter of 2017, subject to the receipt of all necessary regulatory approvals and the satisfaction of other customary closing conditions. On closing, the sale will complete the Company's exit from the Swan Hills area and provide it with additional financial liquidity.

The Company expects to provide an update to its fourth quarter and full year 2017 guidance following the closing of the sale.

BMO Capital Markets Inc. acted as financial advisors to Pengrowth on the transaction.

Advisory Regarding Reserves and Production Information

All reserves and production information herein is based upon Pengrowth's company interest (Pengrowth's working interest share of reserves or production plus Pengrowth's royalty interest, being Pengrowth's interest in production and payment that is based on the gross production at the wellhead), before deduction of royalty obligations and using GLJ's January 1, 2017 forecast prices and costs as disclosed herein. Numbers presented may not add due to rounding.

Caution Regarding Engineering Terms:

When used herein, the term "boe" means barrels of oil equivalent on the basis of one boe being equal to one barrel of oil or NGLs or 6,000 cubic feet of natural gas (6 mcf: 1 bbl). Barrels of oil equivalent may be misleading, particularly if used in isolation. A conversion ratio of six mcf of natural gas to one boe is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
